- ✓ The brake must hold the rated load automatically when power or control is lostCorrect
- C. The brake must be manually applied by the operator whenever the hoist is stationary
- D. The brake must be capable of lowering the rated load at a controlled rate without power
Why B is correct
NAVEDTRA 14343 §9-4 specifies that cargo winch brakes must hold the rated load automatically when power or control is lost. This is a fail-safe requirement; the brake engages without operator action upon loss of power or control signal.
